It is the contrary in many ways to the recently evolved Just In Time manufacturing system.
In JIC, manufacturers need to maintain large inventories of supplies, parts, warehousing resources, and extra workers to meet production contingencies.
If the JIT response contingencies are too slow or fail to keep production flowing additional costs may be incurred.
Under these circumstances the additional costs due to maintaining extra storage, resources, and system resiliency may potentially be more cost effective than using a more efficient JIT system.
[1] A JIC examples of buyers would be the military or hospitals who need to maintain large inventories because waiting for JIT producers to ramp up production for needed supplies may result in losses (i.e. wars, lives).
